Fictional example result
Option A has the lower unit price.
| Measure | Option A | Option B |
|---|---|---|
| Price per 100 g | $0.40 | $0.45 |
| Whole packages | 2 | 3 |
| Amount bought | 1.8 kg | 1.5 kg |
| Amount left over | 300 g | 0 g |
| Package spending | $7.20 | $6.75 |
Option B requires $0.45 less spending for the required packages.
The lower unit price may require more spending for the whole packages you need. Unit prices are rounded to four decimal places; package spending uses the prices in cents that you entered.
Before choosing
Check the food and the trip too.
Compare products that fit your needs, using prices on the same basis. A size conversion does not resolve a different food type, ingredient or quality. This calculation uses your entries, not observed store prices.
Consider offer conditions, taxes, travel, delivery and the risk of waste before deciding where to buy.
